Abstract

L'invention concerne un dispositif de mesure pour mesurer un flux de fluide qui est dû à une différence de pression et s'écoule à travers un corps creux vers un consommateur, le dispositif de mesure comprenant: une chambre de mesure pour recevoir un flux à mesurer, un conduit d'amenée par lequel le flux à mesurer parvient dans la chambre de mesure et qui sert à la liaison entre la chambre de mesure et le corps creux, un conduit sous pression pour la liaison entre la chambre de mesure et le consommateur, un dispositif de capture qui empêche, en position d'utilisation du dispositif de mesure, une sortie du flux à mesurer parvenu dans la chambre de mesure, un canal de passage par lequel le flux de fluide à mesurer est amené du corps creux au consommateur, une extrémité du canal d'amenée orientée vers la chambre creuse se trouvant dans le canal de passage. L'invention concerne également un ensemble comprenant un dispositif de mesure et une niplette ainsi qu'un procédé de mesure du flux de fluide avec un dispositif de mesure.
